Ask HN: Resources for a Green Senior

[Python3267]

Howdy y'all,

I'm about 5 years into my journey as a software engineer. As I've become more senior, I've taken on more responsibilities (Shocker, I know). I am currently spec'ing out a new set of servers for a new service we're spinning up and I was wondering what resources people had for both technical writing and career advancement for a green senior engineer.
